4.6 Conformance inspection. This inspection shall consist of the inspections and tests specified in table II and
4.6.1 Inspection lot. An inspection lot, as far as practicable, shall consist of unit or exterior (shipping) packs
produced under essentially the same conditions and offered for inspection at one time. For the purpose of selecting
samples to be inspected and tested for compliance with the requirements of this specification, either items in process
or completed packs except as stated herein, may be combined into lots without regard to individual items, contracts,
or the quantities therein. Unit packs of the same size that are made from the same packaging materials may be
grouped together except when item complexity, item value, or the complexity of the preservation method warrants
that the inspection of such items be performed on a separate basis. A separate application of the sampling or
inspection procedure shall be made on these items. The combination of items to be subjected to inspection shall be
determined by either the Government or the contractor, subject to the approval of the Government.
